Patented June 11, 1907.

Application led November 28,1905. Serial No. 289,397.

To a/ZZ whom, it 711/011/ con/cern:

Be it known that I, CHARLES D. PLYMP- TON, a citizen of the United States, residing at Needles, in the county of San Bernardino, State of California, have invented certain new and useful Improvements in IVindmills; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to wind mills.

One object is to provide a wind mill embodying such characteristics as to utilize the variety and quantity of natural air currents in the propulsion and operation of the mill.

Another object resides in the provision of a wind mill constructed and arranged to present its wings automatically in the direction of the wind and thereby create power for use at distant points and for the pumping of water from wells.

lith these and other objects in view, the present invention consists in the combination and arrangement of part's as will be hereinafter more fully described, shown in the accompanying drawings and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, siZe and minor details may be made, within the scope of the claims, without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings: Figure 1 is a side elevation of my invention partly in section. Fig, 2 is a top plan view. Fig. 8 is a detail view of the operating lever and the plate upon which it is pivoted. Fig. 4 is a detail view of a latch.

Referring now more particularly to the accompanying drawings', the reference character 1 designates a base block provided with a perforation 2 in which is fitted a casing 3 provided with an upper peripheral flange 4 designed to engage with the top of the base block 1 to support the casing therein.

The reference character 5 designates an inverted U-shaped frame whose legs 6 are provided with feet 7 by which the frame may be set up. The bight portion 8 of the U- shaped frame is provided with a perforation 9 designed to aline with the aforesaid perforation 2 of the base block 1 and in this perforation of the bight portion of the frame 5 5 there is fitted a bushing 10.

Fitted through the perforations 2 and 9 and the sleeve 8 and bushing 10 is arranged a rotatable shaft 11 which depends mainly for its support upon the base block 1. This shaft 1l adjacent the bushing 10 is provided with a groove 12 surrounding which is a sleeve 13 for a purpose presently explained.

Upper and lower collars 14 and 15 are secured to the shaft 1l in spaced relation with respect to leach other and u on .the upper faces-of each of these collars tfiere is disposed a series of radiating arms 16 and 17 respectively. Bridging these upper and lower arms at' the outer extremities thereof are pairs of wings 18. It will thus be understood that there is but one pair of Wings connecting each alining upper and lower radiating arms 16 and 17 and reference to the drawings will disclose that these wings are hingedly connected to the respective upper and lower arms by means of suitable hinges 19 so that they may spring outwardly' from the arms when turned in the direction of the wind or lie close thereto when being carried in the same direction in which the wind is blowing. It might be remarked that these upper and lower radiating arms 16 and 17 are braced by means of suitable bolts 20 and that the arms are prevented from sagging by reason of tie rods 21 secured to the upper arms and to a plate 22 secured upon the upper end of the vertical shaft 11.

When the wings 18 are traveling in the di rection of the wind and are consequently thrown back into engagement with the radiating arms 16 and 17, they are automatic' ally locked against the latter by means of suitable catches 23, there being two of these catches pivoted intermediate their ends by means of a suitable pivot pin 24 to each of the lower radiating arms 17. Each catch is provided with a hooked end 25 for engagement with the corresponding wing 18 and is held to normally throw its hook into engagement with the wings by reason of a spring 26 secured to one end thereof and to the corre sponding radiating arms 17. These catches 23 are provided each with a perforation 27 adjacent its pivot through which is passed a wire 28, which wire 28 passes over a sheave 29 secured to the under face of the corresponding lower radiating arm 17 and is connected in any suitable manner to the flange portion 30 of a sleeve 81 mounted to slide longitudinally of the shaft 11. Connecting this sleeve 31 is another wire 32 leading downwardly through the aforesaid groove in- IOO IIO

closed by the sleeve 13 for connection with a link 33 having one end pivotally connected to the projection 34 of a hand lever 35 pivoted in any suitable manner at its inner end to a plate 36 secured upon the vertical shaft 11 intermediate the base block 1 and the bight portion of the frame 5. When this lever 35 is thrown outwardly of the catch 37 of the plate 36 the catches 23 are so disposed as to lock the wings 18 against outward swinging movement and consequently in order to release the wings 18 from engagement with the catches 23 so that the wings may swing outwardly ofthe radiating arms, it is simply necessary to force the lever 35 downwardly into engagement with the catch 37.

From the foregoing, it will be understood that the wind mill may be readily thrown into and out of operation and that it may be quickly put into operation by manipulating the lever 35 to release the wings 18 from engagement with the catches 23.

Mounted upon the vertical shaft 11 imme# diately above the sleeve 3 is a collar 38 about which may be secured a belt or the like (not shown) for the transmission of power to distant points. The upper end of this collar 38 is provided with teeth 39 through the instrumentality of which power may be transmitted to a distant point in a manner well understood. The lower extremity of the vertical shaft 11 is provided with a disk 4() which is secured thereto in any suitable manner and which performs the function of a crank to which may be secured a crank pin 41 for connection with a pum rod in a manner well unlerstood for the iifting of water from a we l.

In order to limit the outward swinging movement of the several pairs of wings, a pair of stops 42 is secured to each arm 16, as shown in Fig. 2. These stops are disposed upon the arms at right angles thereto, and extend laterally therefrom in the direction opposite to that in which the shaft 11 rotates. y x/Vhen the wind, therefore, blows in the direction indicated by the arrow in Fig. 2, and the shaft is rotated counterclockwise, the wings will be held close against the sides of the arms until each arm passes the dead center line (so to speak) when the wings will be free to move outwardly under the pressure of the wind, into contact with the stops, as indicated by the reference numeral 42 in said figure.

What is claimed is: y

1. A windmill comprising a frame and a base block, a vertical shaft journaled inv the frame and base block, upper and lower collars arranged in spaced relation upon the shaft above the frame, radiating arms secured to each of the collars, a pair of wings hingedly connected to the outer ends of said arms, a pair of spring-actuated catches pivotally mounted upon each of the lower radiating arms for engagement with the corre spending wings of the latter to hold the same against swinging movement, a sheave secured to each of said lower arms, a collar bolts between the corresponding upper and i lower arms for bracing them, a plate secured to the upper end of the vertical shaft, tie rods connecting the said plate to the upper radiating arms, the aforesaid shaft having a groove in one of its sides, a sleeve embracing the shaftadjacent said groove, a second sleeve mounted for sliding movement above the first named sleeve, a pair of spring actuated catches pivotally secured upon each of the lower radiating arms for engagement with thecorresponding wings of the latter to lock the wings against swinging movement, a sheave mounted upon each of the lower arms, a connection between the respective pairs of catches and the said slidable sleeve, the corresponding connections passing over the corresponding sheaves, a lever pivotally mounted upon the vertical shaft, and a connection between the lever and the slidable sleeve for moving the latter, the last named connection passing inwardly of the first named sleeve and lying in the groove of the shaft, and means secured upon the shaft for transmitting power to distant points.

In testimony whereof, I affix my signature, in presence of two witnesses.
